TLVH431CLPE3

Overview

The TLVH431CLPE3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of up to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of 1.5% and a maximum temperature coefficient of 138 PPM/°C. It supports a maximum cathode current of 60 mA with a minimum operating current of 100 µA. The component functions across a temperature range of -40°C to +125°C and is housed in a TO-92-3 through-hole package.

Feature Summary

• Adjustable output voltage capability via external resistor divider
• Low operating current suitable for power-constrained designs
• Wide operating temperature range ensuring stability
• Precision shunt regulation topology

Applications

• Battery-operated equipment
• Switch-mode power supplies
• Data acquisition systems
• Energy management circuits

Procurement Notes

Verify the specific suffix CLPE3 against the manufacturer's latest documentation to confirm pinout, tolerance, and package details. Check for product change notifications or end-of-life status prior to procurement. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Confirm RoHS compliance requirements match the project specifications.

Selection Notes

Select this component when a low-voltage adjustable reference is required with moderate precision. The TO-92-3 package suits through-hole applications where space is less critical than in surface-mount designs. Compare the 1.5% initial accuracy and 138 PPM/°C temperature coefficient against stricter requirements. Consider the 60 mA sink current limit for load driving capabilities.

Part Context

This part belongs to the TLVH431 series of low-voltage adjustable precision shunt regulators. It serves as a cost-effective alternative to higher-voltage references like the TL431, specifically optimized for lower supply voltages. The series offers various accuracy grades and packages to suit different design constraints.
